Importance of Changing Filters

Choosing an appropriate filter depends on your health, how hard you run your furnace, and how many times you want to change filters.  Contrary to popular belief, in the summer the air conditioning works your blower motor at a higher speed than in winter, therefore going through more filters.  A clogged filter makes your furnace work less efficiently and could lead to bigger problems down the road.

Monthly and Tri-monthly Filters

If you change your filter monthly and you don’t have health issues, the 75 cent filters would work for you.  They catch the heavier debris and dirt that could ruin your blower motor, though they do take out some pollen and mold spores.  If changed monthly, it can do the job.  If you are going to forget to change the filter every month, choose the $4 pleated filter that you change every 3 months.  Its accordion-like appearance allows it to work longer without impeading the airflow.


6 Month to 1 Year Filters

If someone in your family or yourself have asthma or allergies, the $20 or the $40 filters are for you.  Some work for 6 months and others for a year and they can filter out bacteria, dander, odors and smoke particles.  You should wash or vacuum the filter monthly and take other steps to clean up your air and house as well.  Use an air purifier to clean your air up either further!

It is up to you how much you want your filter to do, but I say you and your family should breathe cleaner air, so whatever you do, change the filters when they recommend!
